Figure 22 is an exploded view, with certain parts shown in section, of aprinting unit in accordance with the present invention, and illustratingthe method of dis-assembling the unit for shipment. 7

The present invention has for its object the provision of a novel andimproved printing press particularly adapted for use in the printing ofnewspapers at high speeds. A further object is the provision of anewspaper printing press having an improved lubrication system whichinsures constant and thorough lubrication of all bearing surfaces anddriving gears. Still another object is the provision of a printing presswhich can be shipped in a partially assembled state, and can becompletely assembled by relatively unskilled workmen.

The invention further provides a novel and improved driving means forthe individual printing units, improved bearing adjustment for varyingthe pressure between the plate and impression cylinders. The inventionalso provides novel and improved means for reversing one of the printingcouples of a unit so that the web to be printed may be perfected orprinted in multi-color.

In accordance with the present invention, the printing press comprises aplurality of printing units and one or more folding units preferablyarranged in line, each printing unit comprising a pair of printingcouplesadapted to perfect a web, andwhich may, if desired, bereversed toprint the web invmulti-color. As embodied, suitable driving means areprovided for each of said units, and a drive shaft connecting said unitsextends alongside said line of units. Between each printing unit isprovided a clutch in the drive shaft whereby the line of units may bedivided at any one or more desired points, and

means are provided for driving the individual units by means ofindividual drive shafts driven from the main shaft through a couplingwhich can be silenced at will.

As embodied. each of the units comprises a pair of printing couples,each provided with inking mechanism comprising ink drums arranged insubstantially verticahalinement with the plate cylinder of the'coupleand driven from the plate cylinder together with the usual inkingrollers.

Mean drivenby the vertical drive shaft, are provided for driving thefountain roller and vibrating the inking drums, and other means; drivenby the fountain roller, are provided for operating the ductor roll totransfer ink from the fountain roll to the inking rollersand drums andthence to the plate cylinder. k

In the embodied form of the invention, the gearing for driving thevertical drive shaft from the main drive shaft is formed'as a removableunit to facilitate assembly at the printing plant.

The cylindrical body portions of the inking" drums and fountain rollerare'preferably provided with detachable flanges and shafts at their endswhereby the drums and roller can be removed without removing theirshafts and gears from the side frames in which theyare journalleri....After removing theserelatively heavy bodies, the cylinders and thegearing units,-the side frames may be shipped with certain of theshafts,.bearings and gears in place, thereby avoiding the extensivedisassembly and reassembly hich has heretofore been necessary for shippinewspaper printing presses.

The inking rollers for transferring ink from one inking drum to anotherand to the plate cylinder are preferablymounted in hangers which receivethe anti-friction bearing at the ends of the rollers, and these hangersare preferably 'adapted to pivot abouteither or both of two spacedpivots soas to permit accurate positioning of the inking rollers withrespect to both inking drums oran inking drum and the plate cylinder.

Improved means are also provided for varying the pressure between theplate and impression cylinders as may be required for printing.

As embodied, ineans are provided for continuously circulating arelatively large amount of lubricant and for supplying it to the variousbearings and gears of theunit, and these means preferably comprise apump driven by the press and supplying oil under pressure to the variousmeshes of gears near the top of the unit and to the heavy bearings, aswell as other means for receiving the excess oil from the gears andbearings and leading it to the other lighter bearings and operatingunder relatively Referring now in detail to the illustrative embodimentof the invention as shown in the accompanying drawings} the printingpress comprises a plurality of printing units l which may be ofidentical construction and are arranged in line with each other tosupply the webs printed by them to a folding unit 2, also in line withthe, printing unit. Any suitable number of printing 7 units I andfolding units 2 may be employed, with the-folding units preferablyinterposed between the printing units.

The folding units 2 may be ofconventional construction comprising theusual former 3 and O transverse folding cylinders 9, adapted toassociate, longitudinally fold, cut, transversely fold and printed bythe printing units i.

deliver as separate products the various webs The printing units I eachcomprise a pair of v Bearings 9 are held withintheir sleeves It) bymeans of flanges H and I2 which are bolted to the opposite sides ofsleeves 10, while sleeves J0 are held against angular or axial movementby means of screws I3 passing through the flange l4,"

integral with sleeve l0, and threaded into the frame 8.

Cylinder 5, cooperating with the st or second impression cylinder 6 toform the rear couple of the unit, is likewise mounted in the frames 8 bymeans of its projecting shaft ends l5 on which are mounted rollerbearings I6 seated in eccentric annular sleeves l l, and. retained,therein by means of flange I8, at the right, or by a capping plate 19 atthe left end.

The cylinders 5 and 6 of the forward printing couple are mounted in amanner generally similar to those of the rear couple, except that in theillustrativeembodiment one end of cylinder shaft l is'covered by meansof a plate 19 which also serves to hold the end bearing 9 in place,whereas in the rear couple the cap I9 is applied to the left shaft end15.

At one end of the cylinders, the bearings 9 and iii are held apart bymeans of a spacer ring 20 positioned between the outer races of thebearings and. are a sliding fit in their supporting sleeves,

whereas at the other end of the cylinders the bearings are held apart byspacing ring 2| positioned between the inner races of the bearings andare a press fit on the cylinder shaft. At the ends, the inner bearingsabut against the ring 22 fitted to a shoulder of the shaft 1 or IS. Theinner race of the outer bearings 9 or I6 is pressed inwardly by means ofa spacer ring 23 fitted closely to the shaft and extending between theinner race and an abutting gear or capping plate.

Means are provided for varying the pressure exerted during-printingbetween the'plate cylinder '6 and impression cylinder 5,"anH' for thispurpose eccentric sleeves I! may be minutely sition. 'As embodied, eachsleeve i7 is provided. with a pair of diametrically opposed radiallyextending ears 2% which project into a corresponclin ly enlarged portion25 of the frame re-' angularly moved to and held in any desired pog
